Logwatch is a log analysis program that parses through system logs and generates periodic reports based on criteria specified by the user. These reports are generated immediately after Logwatch has run (normally every night) and can be sent by e-mail to a network administrator.
Logwatch summarizes the logs from multiple machines in a single report, which can streamline network maintenance and speed up incident response. Logwatch is written mainly for the Linux operating system but supports log analysis across multiple platforms. Logwatch recognizes the output of many popular programs. The user can write plug-ins for programs not supported, based on instructions included with the download.
